A comment on Bash process substitution.

I sometimes use it to do parallel greps on large files:

  zcat large_file.gz | tee >(grep -F pattern1 > pattern1_results.txt) >(grep -F pattern2 > pattern2_results.txt) > /dev/null
If you stick _pv_ between zcat and tee you can even get nice info about the progress.
